Windows 10: "activate windows" popup every 30 seconds - but my windows is activated

I've already read many posts here about actions to take. As far as I can tell my windows is activated. I've had this computer for years but changed a few parts over 4 months ago and suddenly this week I start getting the pop up to activate windows every 30 seconds or so.

Windows Vista Activation

I have 4 sytems in my home running vista(1 ult.-3 prem).The ultimate & 1 premium took SP1
wthout a hitch.1 premium required re-activation?,The other premium did not list SP1 in windows up-date,So i manually installed it without any re-activation required.
Also have to add that SP1 has increased performance in every comp.The ultimate machine actually got a 1,100 point increase in 3d 06 without any other changes at all.
